Zastupljenost Dirofilaria immitis, Borrelia burgdorferi, Anaplasma spp. i Ehrlichia spp. kod nevlasničkih pasa na području Beograda

Abstract

Bolesti pasa koje se prenose vektorima predstavljaju oboljenja virusne, bakterijske ili parazitske etiologije, koja se najčešće prenose hematofagnim artropodama, komarcima i krpeljima. Cilj ovog rada bio je da se ispita prisustvo infekcija čiji se uzročnici prenose komarcima (Dirofilaria immitis) i krpeljima (Borrelia burgdorferi, Anaplasma phagocytophilum/A. platys, Ehrlichia canis/E. ewingii) kod nevlasničkih pasa na teritoriji Beograda. U periodu od septembra do decembra 2015. godine sakupljeno je 86 uzoraka krvi od klinički zdravih nevlasničkih pasa iz različitih beogradskih opština. Svi uzorci testirani su modinikovanim Knott-ovim testom i komercijalnim SNAP® 4Dx Plus® Test-om. Infekcija izazvana barem jednim od ispitivanih uzročnika ustanovljena je kod 27,91% pasa. Najzastupljeniji uzročnik bila je D. immitis, koja je dijagnostikovana kod 17,44% životinja. Na prisustvo antitela protiv Anaplasma spp. pozitivno je bilo 9,30% pasa, dok je 2,33% jedinki bilo seropozitivno na B. burgdorferi, odnosno na Ehrlichia spp. Koinfekcije sa dva patogena zabeležene su kod 3,49% pasa. Rezultati ovog istraživanja pokazuju da su nevlasnički psi na teritoriji grada Beograda izloženi delovanju različitih vrsta zoonoznih uzročnika koji se prenose komarcima i krpeljima, zbog čega treba preduzeti odgovarajuće mere za suzbijanje ovih artropoda.

Vector-borne diseases are caused by viruses, bacteria or parasites transmitted by hematophagous arthropods, mainly mosquitoes and ticks. The aim of this work was to study the presence of pathogens vectored by mosquitoes (DiroGilaria immitis) and ticks (Borrelia burgdorferi, Anaplasma phagocytophilum/A. platys, Ehrlichia canis/E. ewingii) in stray dogs from Belgrade. From September to December 2015, 86 blood samples were collected from apparently healthy stray dogs in different Belgrade municipalities. All samples were analysed using modiNied Knott’s test and commercial SNAP® 4Dx Plus®Test. Infection with at least one pathogen was detected in 27,91% of investigated dogs. The most prevalent agent was D. immitis that was diagnosed in 17,44% of animals. Antibodies against Anaplasma spp. were found in 9,30% of dogs and 2,33% individuals were seropositive to B. burgdorferi, as well as to Ehrlichia spp. Coinfections with two pathogens were recorded in 3,49% of dogs. Results of this research show that stray dogs in Belgrade are exposed to different zoonotic pathogens transmitted by mosquitoes and ticks, indicating the need for appropriate control against these arthropod species.
